The beast was back, it came in the night every night. Just not in the same shape or form. It tormented him, and whispered in his ear. No one knew about it. He could tell them. That's why he went to Africa, to get away from them. No one even questioned him about going there. No one noticed that he alone, didn't have any back up.
Day after day, alone driving from town to town. And walking when he couldn't drive. Looking for peace. But it never came to him. Only the beast, and it whispers.
First the whispers would only talk about killing demons and vampires, and he would listen to it in the dark of the night. But soon it started in the friendly demons, then to humans.
After fighting off some vampires one night. And Saving a few people. He stood back and looked at them. They were like he was when he started. Weak, soft, easy meat. Then it hit him. He wasn't weak anymore. With a shack of his head, he walked out into the welcoming darkness.
The last anyone ever saw of him, was a flash of neon green eyes. At last Xander found peace.
